Yes, that was the plan, but I can't confirm that it worked out as I don't have any physical 68k hardware in front of me right now. If you can confirm this on your Atari Falcon, that would be great. (It appears that a QEMU-emulated Mac does not benefit from having a clocksource that's more accurate than the 'jiffies' clocksource, in spite of "clocksource: Switched to clocksource via1".)
